Current DIY Acoustic Panel Design?

Postby Jez Corbett » Tue Dec 18, 2018 4:34 pm

Just been browsing through this subforum the last hour or so as I'm looking to make some simple panels to fix the worst issues in my home setup, but it seems all the stickied threads are very out of date - sadly none of the Links in Zukan's thread work any more, and many of the projects never finished :(

Just wondering where I can find a good design for rockwool based panel traps? Got the assistance of a carpenter because I never had an affinity for it and got a D in GCSE CDT (i.e. 'Woodwork'), but not sure what the best approach is these days other than 'stick a slab of rockwool in a frame and cover it in fabric'.

That's pretty much it as I understand it. Cheap, acoustically porous, fabric for the back, something nice looking and easy to get neat, like Cara, for the front. Robert is your mother's brother.
Mount away from the wall for better bass control and across the corners to tame things there a bit. Make sure you've got your mirror points covered.
Then listen/measure again and see how things are shaping up.

As above, that approach pretty much covers it for simple panels. When I made my panels up I built one frame to sit around the rockwool, streched the fabric right around to the back of that and stapled it to give a nice flat, square finish to the front of the panel, and then framed up the outside with something more decorative separately.

I used the Camira Cara fabric that blinddrew mentions, there are cheaper options about but it gives a lovely finish, and is very easy to work with. I managed to get a pretty good result having never worked with fabric of any sort before.

I've got a load of pictures I can dig out if they're of any use.

That's how I did most of mine, using slabs of Rockwool RW3. 1200 x 600 x 50mm with a density of 60kg.m3. I've linked to the Studiospares page below but shop round as I got mine much cheaper from another supplier.

I made frames from 2 x 1 PAR and wedged the Rockwool inside then covered the front in Cara fabric and the back in decorators dust sheet material from B&Q. The bass traps were different as I based them on Studiotips Super Chunks.

Studiospares might be the best source at the moment - when I looked a few weeks ago the cheaper suppliers had none in stock and all mentioned delivery problems. Studiospares still had stock.

I'm having that problem at the moment as well. When I built my first batch I got a load quite a bit cheaper from a builders merchant, now I'm looking at making some more up they don't have any stock and aren't looking too different on price.

They will, but they take about 2.5 clicks off your authenticity. You might need to add an extra whistle part to compensate.

Metal pads definitely won't work.

You could always use Folkrockwool panels.

I get my rockwool from BSO...

then to go for 12-14cm wood strip to leave a gap behind, and drill out the sides with a large hole cutter to keep the weight down, useful in easing ceiling cloud based paranoia..

I also used Cara....

Hmm ... are the GIK bass traps basically the same as homebrew panels, or something different?

At these prices, it might be hard to justify getting them made myself.

I believe they use the same materials as the ones I built myself. Probably, better made and more professionally finished though :smirk: . They do look excellent value for money but I reckon I saved 35%+ by building my own.

I did a job recently where I built 8 panels and fitted them for about the same price as 8 of the full size GIK panels. DIY is certainly cheaper provided you are making a reasonable number of panels. If you don't want to DIY then keep looking as I'm sure I've seen 1200x600 panels for around £50 (it was either Studiospares or Ebay).
